Simple BSA Scorpion Questions.

[0liver]

Hello,

I have recently bought a Mark 2 .22 BSA Scorpion on Gunstar.

My question is about the sights. They are set as low as possible but the gun consistently shoots very high.
It is accurate if I compensate and aim about 4" lower than the target.

Is this a known thing: any advice ?

Also, I have seen pictures of Scorpions with a frontsight hood; I can't see how that would fit on and still allow the cocking aid to work unless it just clips on ; were the hoods fitted on all Scorpions ; there are no grooves on my frontsight ?

Also what pellets would anyone recommend ?

Thank you.
